LiquiShield Concrete Guard is a water-based guard formulated to improve gloss while adding substantial protection against stain and etch. Low-odor guard is easy to apply and requires only two coats to cover 3,000 to 4,000 square feet per gallon. LiquiShield eliminates the need for floor finish and conventional coatings by resisting scuffs, black marks and soil. It will not peel, flake or discolor. Breathable formula is ideal for concrete, terrazzo and other porous stone surfaces.
